About
The hybrid gas density monitor combines self-acting monitoring and continuous density measurement of insulating gases in one device. The digital RS485/Modbus output allows the parameterisation of gas density, gas pressure and gas temperature output data. Trend analysis helps to detect possible leakages sooner, provides data for preventive maintenance measures and therefore facilitates compliance with greenhouse gas regulations. This precise and maintenance-free hybrid density monitor is reliable in operation over decades for indoor and outdoor applications.
